Title: A New LFM Fuze Distance Deception Jamming Suppression Arithmetic
Abstract: To solve the problem of linear FM( LFM) fuze distance deception jamming,a new jamming suppression method is studied which combines random slope and blind source separation( BSS). This method adopts discriminated mechanism,which can make the enemies difficult acquire the fuze's signal parameter. So,the simple method can be used to suppress the jamming. When the random slope is invalid,BSS can be used to separate the echo and jamming,and the spectrum continuity principle is used to acquire the intact signals,and then the digital radio frequency memory( DRFM) phase quantification's characteristic is used to distinguish the echo and jamming. The experiments results indicate that when the jamming signal' s slope is greater than four percent,the random slope jamming suppression has great effect,and there is less than ten percent to use the method of BSS. So,the calculated amount can be reduced greatly.
